At least Simon the GPZ coils can be sold to make a patch coil, if they don't trust damaging their own coil.😜

What makes me mad with Minelab coils is I have to buy their coils with each detector even when I know it will remain unused, as my choice of detecting does not favour the most general ML size coil. Most of the committed prospectors over the "Minelab era" that I have known had to pay for a ML coil that they did not want and the resale of them is very low as most customers have one also sitting unused.

This YouTube shows the work done, the effort put in by the gold diggers and the change to the environment that occurred during the 1850 - 1890 ......LINK.... for video below.

I had a similar good fortune at and old county football building, where the coins had fallen through the wooden floor gaps of the members private elevated and enclosed grand stand.

Just guessing but it might be in pinpoint mode and not search mode and vice versa due to software update or incorrect wiring for selection of the mode that you choose.

You can see with the amount of over lapping, he is going for depth no ground coverage.

My choice is determined by what I am going to use it for. Then look at the views of members on forum have to say particularly this forum.

The main thing with a drag coil is that it is very useful for covering a large open area that is a "virgin patch" area to see if there is gold in it. Then to find the majority of the gold you have to grid/chain the area with a normal/small coil and then a large hand held coil in the deeper ground as the depth of the smaller coil targets get deeper. Just think how many of your nuggets would of been detected with a 25+ inch coil if you did not know they were there, however very deep larger nuggets would be missed with a small coil. I would of been lucky if I used a very large coil more than 1% of the time. So the best spots to use a drag coil is in large clear non flogged/known locations, I hope this lets you know what you are getting into.

From Wikipedia Human horse power that might be of interest. When considering human-powered equipment, a healthy human can produce about 1.2 hp (0.89 kW) briefly (see orders of magnitude) and sustain about 0.1 hp (0.075 kW) indefinitely; trained athletes can manage up to about 2.5 hp (1.9 kW) briefly and 0.35 hp (0.26 kW) for a period of several hours.

I have found a few new ground patches, but in most of them only one or two nuggets would of been found with a drag coil and even less with the size that you desire, the rest you need to grid by hand. How ever you can cover a lot of ground with a machine dragged coil in shorter time in poor ground. I'm sure other will give you their opinions of what is worthwhile, best of luck.

The Australian situation is .......1c and 2c coins will continue to be legal tender: they can still be used to purchase goods and can be deposited with financial institutions in the normal manner." Both coins were withdrawn from circulation commencing in February 1992.

The area of the holes compared to the area of the exposure surface for the holes would give the best thruput of sand. The maximum dimension of the holes related to the target you are chasing should be selected. However do we need to be so concerned on type as most work.

That is the worst detecting skills I have seen. The ground that his missed would be more than 50% of the ground that he was swinging over. To me it looked like a setup, and the gold was found elsewhere. 😒

I see you manage to focus OK on the person behind the kid. 😉

Thanks for that information Steve. I will try to leave some gold for others at those two dozen spots that you have listed. 🤑

Hunterjunk, I like your 1906 Launceston Centenary find. Have not seen one of those before, great find. It must be unique having two Tasmanian tigers (thylacine) on it.

BJ the 7 areas are the states, note I included Tasmania 😁

It is very hard to find gold in virgin location. When the nuggets were laying everywhere in 1979-80 I spent about half a years working hours searching virgin ground with no finds. It taught me you have to be in the right ground near (a few miles) known mines or diggings. However once you have got the eye and feel it can be very rewarding. Have a look at an old post of mine.

All seven areas have gold. Just keep clear of my patch. 😁

Some Photos from Vic and WA Aus. Whites 6000D and Aus Whites GoldMaster from early 1980s on the beach after Gold jewellery. Panning South of Ballarat. Note proper Steel Gold Pans. 😁 VIC. Claim I took out after finding 26+ oz in one day. The brother-in-law on claim. WA. Where I found my largest bit, 3500 gm with nearly 17 ounces of gold. General Area of above. Same area but wide view of general spot. A photo that was used on another forum that has now gone the way of many others. Four hundred small bits about 0.3 to 0.4 gm each.

Erik have you checked nice sandy boat landing points for picnics around the island. It might not be the best for coins but rings, watches and necklaces could be at these spots and they would not be hit by weekend detectorist. Hope you are still looking after MY BEACH.

Sound like AI is smarter than some people I know that are convinced they can use it with great success. 😁

Jasong to test AI I would ask it what is the best "long range divining device" to see the results.

Hey that's pretty cool. It's like a six year old repeating the ads on television. Clever. That seems to be the way most people get their knowledge these day. Where as they should use experience and effort on the ground using a device to get the best results for their location..

Look after it, and don't overload it with the nuggets that you will find.
